Standard-income Long Island homeowners should not assume they’ll get a large NY-Sun rebate – Long Island’s program works differently than many expect in 2026. The program still funds Long Island, but the incentive confirmed today on NYSERDA’s own dashboard is aimed at lower-income households – not the general public. If you’re budgeting for solar in 2026, here’s exactly what’s real, what’s not, and what to check before you sign a contract.
HOW NY-SUN WORKS
NY-Sun is New York State’s solar incentive program, administered by NYSERDA (the New York State Energy Research and Development Authority). It pays a per-watt cash incentive directly to participating installers, who pass the savings on to homeowners as a lower upfront price.
The program is organized into regional “blocks” – Long Island, Con Edison territory, and Upstate New York each have their own. As homeowners in a region complete enough projects to fill a block’s megawatt (MW) allocation, that block closes and the next one opens, usually at a lower incentive rate. This step-down structure is why the rebate available today looks very different from what was available a decade ago.
WHAT LONG ISLAND HOMEOWNERS CAN CONFIRM TODAY
NYSERDA’s official Long Island Dashboard names one incentive clearly: the Affordable Solar Residential Incentive.
Affordable Solar Residential Incentive: $0.40 per watt of installed capacity, for households at or below 80% of the Area Median Income (AMI) for their area.
For a typical 8 kW residential system, that works out to roughly $3,200 off the installed cost – before any additional tax credits.
Long Island’s standard-income residential blocks are tracked on the same dashboard and shift over time as applications are filed. Rather than quote a number that could be outdated by the time you read this, the reliable way to know what applies to your project is to have your installer check the live block status, or check it yourself at NYSERDA’s Long Island Dashboard before signing a contract.
HOW TO CHECK YOUR ELIGIBILITY
- Estimate your household income relative to your area’s AMI. NYSERDA and HUD publish AMI figures by county — Nassau and Suffolk County limits are set separately, so use the correct one for your address.
- Ask your solar contractor if they’re a NY-Sun participating installer. Only approved contractors can apply the incentive to your project; it isn’t something you file for yourself afterward.
- Request written confirmation of your incentive amount before signing. A reputable installer will show you the incentive as a line-item credit on your proposal, not a vague estimate.
- Check the current block status yourself if you want a second opinion, using NYSERDA’s public Long Island Dashboard.
WHY THIS MATTERS MORE IN 2026
The federal 30% residential solar tax credit (Section 25D) ended on December 31, 2025, for homeowner-owned systems. See our full guide to what changed with the federal solar tax credit. With that credit gone, every remaining state and utility incentive carries more weight in the total math of going solar. Confirming exactly what you qualify for – rather than assuming a number from an older article or a competitor’s ad – protects your budget and keeps expectations realistic from day one.
Understanding the real NY-Sun rebate Long Island homeowners qualify for today matters more than ever, now that the federal credit is gone.
WHAT'S STILL AVAILABLE TO LONG ISLAND HOMEOWNERS
Affordable Solar Residential Incentive – $0.40/watt for income-eligible households (see above)
NY State Solar Energy System Equipment Tax Credit – a state tax credit on your system cost, with unused credit carried forward to future tax years. Confirm the current percentage and cap with a tax professional, since state programs are periodically updated.
PSEG Long Island net metering – credits you for excess solar power sent back to the grid.
Property tax exemption – the added home value from your solar system can be exempt from a higher property tax assessment.
– Energy storage incentives — a separate NYSERDA incentive applies to battery storage paired with solar, and LIPA’s Dynamic Load Management (DLM) program offers additional value for eligible customers who allow limited utility control of their battery during peak demand.
